Spots is a simple App that allows people to experience remote touch; so it requires at least two people! 
When you start Spots, you see an empty grey screen. When you drag your finger across the screen, a
 circle follows your finger. These actions are broadcast shared with other people running Spots. When other people enter this space, a vaguely visible spot appears on your screen with a soft sound and their dragging actions leave fading traces. When your spot and another overlap, a vibration can be felt and a fading ripple is visible, showing a trace of your touch.

We'd love to hear what you felt meeting others in this way.
